CVE-2024-50233

System crash via zero-rate frequency calculation

Published Nov 9, 2024 · Updated May 11, 2026

Divide-by-zero in the Linux kernel AD9832 IIO driver allows local users to crash the system by writing a crafted frequency value. The ad9832_write_frequency function can pass a zero clock rate and text-derived output frequency to ad9832_calc_freqreg, which divides by that rate. Triggering the fault requires local write access to an active AD9832 device attribute, and the resulting kernel exception can interrupt the system.
